My invention relates to lunchcounter stools orseats of the type having a seat portion supported on 4a pedestal which. is secured to the floor, and relates inparticular to a construction and cooperation of parts whereby the support of the lunch counter stool may be secured rigidly to the oor by means concealed from View and which does not require the extension of wrenches or tools Within the pedestal. i Y' It is an object of the invention to provide a lunch counter stool having a pedestal which may extend as a continuous member from a position adjacent the lower face of the seat to the surface of the oor and which may be'rigidly secured to the floor without use of lag screws or the like disposed with the heads thereof visible around the base of the pedestal.

A further object of the invention is to provide a lunch counter stool having a pedestal extending as a continuous member from the seat to the floor and having a downwardly faced recess therein to receive a securing member which is attached to the fioor prior to the placing of the lower portion of the pedestal thereover, there being locking means operative between the securing o-r anchoring member and the pedestal to lock the pedestal to the securing or anchor member in response to rotation of the pedestal.

A further object of the invention is to provide a lunch counter stool construction having an anchor member which requires a minimum of ma chine operation, or no machining at all, in the manufacture thereof, and which anchor member, when employed to secure the stool to the door, is entirely concealed within a recess in the bottorn of the support.

A further object of the invention is to provide a lunch counter stool havinga 'pedestal with an Further objects and advantages of the invention' will be brought out in the following part. of the specification. i i

Referring to the drawing which is tivepurposesonly:

Fig. 1 is a view showing a preferred form of my invention.

Fig. 2 is an enlarged fragmentary vertically sectioned view of the lower. portion of the pedestal with the anchor member therein.

Fig. 3 is a cross sectiontaken'as indicated by the line` 3-3 of Fig. 2 showing the cooperating lugs of the pedestal `and the anchor member in fo-r illustraengagement.

enlarged lower end to form a base of artistic appearance, this base having a downwardly faced recess, and means securable to the floor in the position selected for the lunch counter stool, and having a part adapted to projectinto the recess when the lower part of the pedestal is placed thereover, and means for locking these parts together.

\ A further object'ofthe invention is to provide an anchor member having a lower face to engage the floor and means for rigidly securing the anchor member tothe oor. Above the surface of the floor the anchor member has radially projecting lugs adapted to engage lugs on a pedestal which is placed over the anchor member and to secure the pedestal rigidly in a position extending upwardly from the anchor member.

Fig. 4 is a sectional View similar to Fig. 3 showing the lugs of the anchor member and ofthe pedestal disengaged.

In Fig. 1 I show a stool assembly A secured on' a floor I0 in cooperative relation-,to a counter I I. This stool assembly includes a seat I2 and a support I3 for theseatshown in the formof a. column or pedestal havingv at the bottom thereof a wall I4 Yenlarged so as to form a plate on fiange I5 which is provided with a peripheral face I6 to engage the floor-I0, as shown in Fig. 2. In the preferred practice of the invention, the seat is provided with a back I'I and iscarried by the pedestal I3 so as to rotate around a vertical axis, there being camv means i8 tending to rotate the seat I2 into a position facing the counter lI.`

In the preferred practice of the invention the pedestal I3 is cast in one' continuous piece without intermediate joints. yThe invention makes possible, the provision of an artistic appearance, and by elimination of externalcrevices such as would be caused by joints the maximum condition of sanitation is maintained. As shown in Figs. 2, 3, and .4,.the wall I4 at the lower end of the pedestal I3 is enlarged and deiines a portionof a downwardly faced recess 20 in the lower part vof the pedestal I3. From the .wall Il a plurality of lugs 2I project within the recess 2i) toward the vertical axis of the pedestal i3, there being spaces 22 between thesev lugs ZI. ployment of the term lugs in conjunction with the numeral 2'I, I meanwalls so formed as to have upwardly faced surfaces 23 to serve a purpose which will be hereinafter described.

Within the recess 20, and concealed thereby,

there is an anchor member 24 preferably com- In elnv when the pedestal I3 is placed over the anchor member 24 with such anchor member 24 received in and concealed within the recess 20. As will be noted in Fig. 4, the lugs 28 of the anchor member 24 are slightly smaller than the spaces 22 between the lugs 2|, so that as the pedestal I3 is placed over the anchor member 24 the lugs 2| of the pedestal may pass downward through the spaces between the lugs 28 tothe positions thereof shown in Fig. 2. In the use of the term lugs with respect to the members 28 I mean walls so arranged on the body of the anchor member rotation of said support relative to said anchor member to secure said support to said anchor member; a wall on said anchor member having a surface which faces outwardly from the center of said anchor member, said surface being disposed so that its radial dimension from the center of said anchor member decreases in rearward. direction; and screw means extending in wardly through the lower portion of said support into said recess to engage said surface of said y anchor member.

24 as to lie over and engage the upper faces 23V The lower faces 3| of the lugs 28 slope down- Y ward in anti-clockwise direction, and the upper faces 23 of the lugs 2| are preferably slopedl in a cooperative manner so that'when anti-clockwise rotation of the pedestal 30 carries the lugs 2| under the lugs 28, downward pressure will be transmitted from the lugs 28 to the lugs 2| asa result of the cam action produced by the faces 23 and 3|, thereby forcing the floor engaging portion or flange I5 of the pedestal I3 tightly into engagement with the floor'I Il. The invention also includes locking means for preventing. re-` verse or clockwise rotation of the pedestal I3 relative to the anchor member 24, so that the' pedestal I3 cannot be disengaged from the anchor member. A simple form of this locking means consists of a screw threaded through the wall I4, so as to be screwed inward from the position in which it is shown in Fig.4 into engagement with the anchor member 24, as shown in Fig..3. The anchor member 24' provides` a surface 3B. faced outwardly from the central portion ofY the anchor member and which slopes rearward'to'.- Wardthe axis or centralV portion of the anchor. member 24 in the manner ofA av spiral, and the screw 35 is adapted to engage this sloping wall 35. whereby the reaction of the pressure of the screw 35 against the same will. exertaA force tending to rotate the pedestal I3 in anti-clockwise direction relative to the anchor. me1nber'24'. Aslshown in Figs. 3 and 4 this Irearwardly sloping face 3S for cooperation with the screw35 is conveniently formed on the rearward portionr of one of the lugs 28 of the anchor memberA 24..

To give an idea of the simplicity and economy cf the combination hereinbefore disclosed, it

may be remarked, that in the present use. of ,4.

the invention the anchor member 24'has a diam:- eter of about 41/2inches and isv readily cast.: to the form shown. In View ofthe factthat itis entirely concealed whenin use, it may befemployed, without machining, in the naturalstate inwhich it is received from the foundry. l
